Highly Desirable Skills: Experience in one or more of the following areas would be advantageous; we do not expect candidates to have experience across all of them: * Familiarity with techniques for evaluating video codec performance, including bitrate/quality/latency trade-offs and objective or perceptual video quality metrics (such as PSNR and VMAF). * Familiarity with compressed video bitstreams and codec signalling, such as NAL units/OBUs, parameter sets, profiles/levels and supplemental enhancement information. * Experience developing native video players, media frameworks or codec pipelines on TVs, set-top boxes, consoles, mobile devices or other embedded platforms. * Experience configuring or integrating hardware video encoders or decoders. * Deeper knowledge of H.264, HEVC, AV1 or other current and emerging video codecs, beyond high-level API configuration, such as reference structures, rate-control behaviour, bitstream structure or encoder-specific optimisation. * Experience optimising real-time video for low latency, visual quality or bitrate efficiency. * Familiarity with frame capture, graphics presentation pipelines, framebuffers or GPU/CPU synchronisation. * Experience identifying and reducing memory copies, queueing delays, memory-bandwidth limitations or other system-level performance bottlenecks. * Experience working with system services, daemons, firmware interfaces or other low-level platform components. * Familiarity with techniques such as content-aware encoding, region-of-interest encoding, adaptive resolution or frame rate, alternative reference-frame strategies or similar streaming optimisations. * Experience with Forward Error Correction or other techniques for improving the resilience of real-time media. * Experience with SIMD, vectorisation, cache optimisation or multithreaded performance tuning with instrumentation. * Experience with console or embedded systems development environments. * Experience with Git, Jenkins or similar CI/CD workflows. Why Work in GDFT * Focused on platform-wide technology development * Room to explore and innovate within performance-critical system areas * Work on cross-regional collaborative projects * Flexible and relaxed working environment, with strong support for hybrid work * Opportunities for extensive professional development, technical conference attendance, and participation in internal hackathons ## Description We are looking for an engineer to join the GDFT department, working on the design and optimisation of PlayStation's real-time game streaming technologies. You will contribute to the development of low-latency video streaming systems across current and future PlayStation platforms, working on performance-critical areas spanning frame capture, media pipelines, codec configuration, system services and streaming transport. The role is particularly suited to engineers with a strong C/C++ background and experience working with native video or media systems, including embedded devices, TV firmware, set-top boxes, consoles, or similar. Our work sits at the intersection of product engineering and R&D. Alongside delivering production technology, engineers are encouraged to investigate new approaches to reducing end-to-end latency, improving visual quality and reducing bitrate, using measurement and experimentation to determine where meaningful improvements can be made. What You'll Be Doing * Develop, optimise and maintain low-level C and C++ components within PlayStation's game streaming stack. * Investigate opportunities to reduce end-to-end streaming latency across frame capture, buffering, encoding, transport, decoding and presentation. * Optimise the use and configuration of hardware video encoders, applying knowledge of codec behaviour and low-latency encoding techniques. * Analyse existing media pipelines to identify unnecessary buffering, memory copies, synchronisation delays and other sources of latency. * Use software and hardware instrumentation to measure system behaviour, validate hypotheses and quantify the impact of performance changes. * Investigate and debug issues across user-space applications, system services and daemon-level components. * Prototype and evaluate new approaches to improving streaming quality, latency and bandwidth efficiency. * Work with engineers and researchers across the wider organisation on areas such as codec development, rate control, Forward Error Correction and emerging media technologies. * Contribute technical findings and recommendations to design discussions, working with senior engineers to determine appropriate production solutions. * Collaborate across teams to integrate and validate streaming technologies within PlayStation platform software. * Attend periodic in-person workshops or team events, with travel possible a few times per year.
